well, I have a map which for some reason was broken... and I put a lot of effort in it ("Thr33 Stag3s: P4rt Tw0" is the map) ... I couldn't open it ingame and I wasn't able to open it in the editor too after the miniupdate for the editor - the game crashed or I got a main-menu-screen without the buttons like "singleplayer, co-op, community test chambers, options, exit"... it was very weird - well I deleted it and made it again from 0, but in retrospect I have to say that it's not that tragic if you have the concept in your head, I guess the second version is even better, made some changes and so on :>

A very beautyful map - only thing that's not good: try to avoid situations where the test subject get stucked and has to restart the map (for example if the reflective cube is in the 2nd room and you jump back into the first without a portal behind the fizzler...)oh and if someone wants additional hard maps (which are longer than this one) then please check out my maps^^
